Food Additive Inhibits Longevity Enzyme In Yeast, Increases Cell Toxic
Dihydrocoumarin (DHC), a common additive found in food and cosmetics, has been found to inhibit the activity of sirtuins, enzymes associated with lifespan control in yeast and other organisms, according to a new study led by UC Berkeley researchers. Human white blood cells exposed to DHC also experienced increased cell toxicity and apoptosis. Lower Levels Of Anti-inflammatory Proteins May Contribute To Chronic W
A new study examined cytokine profiles in patients with chronic widespread pain and found that they had significantly lower levels of the anti-inflammatory cytokines IL-4 and IL-10. Researchers Add New Tool To Tumor-treatment Arsenal
A new study demonstrates the potential effectiveness of treating tumors by combining agents that damage DNA with a drug that sensitizes cancer cells to these agents. Researchers Zero In On How The Body Regulates Its Response To Heat Str
An elusive neurotransmitter pathway in the skin may have been isolated by University of Oregon researchers, a discovery that, if confirmed, would be a leap forward in understanding how temperature regulation occurs. In other words, they may have found a major player in the machinery that allows people to release body heat and stay cool. Jefferson Lab Builds First Single Crystal Single Cell Accelerating Cav
Jefferson Lab scientists have, for the first time, successfully fabricated and tested a single cell accelerating cavity made from a single crystal of niobium in the same shape as the low-loss design proposed as an improvement to the baseline for the International Linear Collider (ILC). In preliminary tests, the superconducting cavity's accelerating gradient exceeded the ILC specification of 28 MV/m and eventual goal of 35 MV/m. MPs Reveal Summer Holiday Reading
2007 survey of the summer reading choices of British MPs (Members of Parliament). Features samples of some of the book choices, which include biographies, classics, historical and political titles, Harry Potter, and more. From BBC News. Joint Genome Institute Sequences DNA Of Prehistoric Cave Bears
The genomic DNA sequencing of an extinct Pleistocene cave bear species -- the kind of stuff once reserved for science fiction -- has been logged into scientific literature thanks to investigators from the U.S. Department of Energy (DOE) Joint Genome Institute (JGI). The study, published in the June 2 online edition of the journal Science, has set the research community's sights on traveling back in time through the vehicle of DNA sequencing to reveal the story of other extinct species -- including our nearest relatives, the Neandertals. Mars Research Opens Doors To World's Fastest-growing Economy
ASU's Mars research team took center stage at China's national celebration of science and technology, and tens of thousands of Chinese citizens -- including schoolchildren, scientists, engineers and senior members of government -- took notice. The result was one of those rare events in which planets seem to align, paths and destinies cross, and magic happens. Sleep Apnea Can Be Diagnosed Without Overnights In A Sleep Lab
Exclusively ambulatory techniques and equipment were as successful at identifying and treating sleep apnea as the current method of polysomnography, which requires several supervised overnight stays in a sleep laboratory, according to a study in the Annals of Internal Medicine. Higher Folate Intake Associated With Decreased Risk Of Hypertension In
Hypertension affects an estimated 65 million individuals in the U.S. and many more worldwide. The purpose of this study was to determine whether higher folate intake is associated with a lower risk of hypertension.
